Phono Preamp Reviews

Audiophiles with budget restrictions (most of us, I imagine) could be forgiven for feeling we're afterthoughts to most manufacturers. Even though we probably keep most companies in business by buying their "entry-" or mid-level products, we're always hearing about products designed "without compromise." Waiter, could you bring the reality check, please?

Just as the Trappist Monks of Digital Audio are once again grabbing at the bellpulls to ring the death knell of analog, another fine piece of gear pops up dedicated exclusively to LP playback: the American Hybrid Technology Phono Stage. To one of the Analog Committed, this is good news. That the unit sounds as wonderful as it does is even better news. Anything else? Pull up a pew, Brother.

Other than being well built and high priced ($15,000, $22,000, $60,000), these three phono preamps have very little in common, in design or in sound. One has vacuum tubes, including a direct-heated 5U4G rectifier tube (the Phasemation). Two are solid-state (the PBN and Qualia). Two feature separate chassis for the left and right channels (the Qualia and Phasemation). All three have outboard power supplies. Two come from Japan (the Qualia and Phasemation), one is made in the US (PBN). All three are elegantly built, inside and out. Two are physically attractive, one is lab-grade butt ugly. One has a host of convenience features, including various equalization curves and three inputs (Phasemation). One offers no adjustability whatsoever (Qualia). One has two gain settings and multiple loading options (PBN). Two are designed to be used only with moving-coil cartridges, while the third (Phasemation) can also accommodate moving-magnets. One is fully balanced and dual- differential (PBN), two are not.

At the 2011 Consumer Electronics Show, Herman van den Dungen handed me a surprise: a brand new Kiseki Blue cartridge manufactured from new-old-stock parts. It wasn't mine to take home—only to look at, to prove it was real.

Herman van den Dungen may not be a household name even for audiophiles, but his products are: his PrimaLuna electronics are exported from the Netherlands to the US and distributed by tube connoisseur and collector Kevin Deal for PrimaLuna USA.

In the 1980s, Kiseki was legendary among audiophiles, even if their cartridges' prices were beyond the reach of most. But the brand's history is less well known—and younger analog devotees may not have heard of Kiseki at all.

ModWright Instruments' PH 150 moving-coil/moving-magnet phono stage measures 17" wide by 5" high by 12" deep and weighs 19lb. Knobs on its front panel let you easily make adjustments that with some phono preamps require accessing the rear panel or going inside. Starting at the left, the Select knob offers settings for MC, MM, and Mute. The Gain knob offers levels of 0dB, –6dB, and –12dB. With MC selected, those settings would correspond with 72, 66, and 60dB of gain, respectively; with MM, the numbers would be 57, 51, and 45dB, the last being more typical of most MM stages.

First, let's talk about problems with grounding and hum...

As I began writing this column, the terrible news arrived that Armando "AJ" Conti, founder of Basis Audio, had died of a heart attack at 59. A talented designer of turntables and tonearms, AJ was one of the warmest and more thoughtful people in the High End. Whenever I entered the Basis room at a Consumer Electronics Show, I had to be prepared to spend the next hour or more talking with AJ—not only about audio, but about coffee, motorcycling, metallurgy, or any other of his many passions . . .

Although Swiss-based CH Precision is a relatively young company, its core design team has been involved in high-performance audio for many years. Their website doesn't state the company's age, but something there did provide a hint: Among the design team's previous activities was work for another Swiss company, Anagram Technologies...I hadn't made the connection between Anagram and CH Precision when Raphael Pasche, the latter's electronics design engineer, visited last fall to install CH Precision's P1 dual-mono phono stage and the optional X1, a discretely regulated, outboard linear power supply that's claimed to exhibit ultralow levels of noise. The P1 can be ordered as a stereo preamp for $31,000; add $17,000 for the identically sized X1 power supply. Or one mono P1 can be used for each channel, for $55,000 plus $34,000 for two X1s. Expensive stuff.
